Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500644, here are decompositions:

41 + 500603 = 500644
173 + 500471 = 500644
227 + 500417 = 500644
251 + 500393 = 500644
281 + 500363 = 500644
311 + 500333 = 500644
467 + 500177 = 500644
491 + 500153 = 500644

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 500,644 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
